` My invention relates particularly togliders adapted tobe applied tofurniture tosupport thesame. f y f. .fg

` The object of my invention` is toprovide gliders of an improved type,adapted to be applied to portions of furniture forthe support vof thevsame, and ywhich are adapted to support the furniture while eliminatingnoise to a maximum extent when moving the furniture from place to lace.Glidersmade in accordance with myyinvention 1 are capabley of beingapplied to'anyportion ofanyfkindof furniture to supportthesame, but areapplicable especially to kthe legs orfeet of chairs,

tablessettee's, etc. v vj f Hitherto gliders provided forjsupportingfurniture have had many disadvantages-' As originally made,such gliders`were comprised merely ofa large metal head havinga stem adapted to bedriven into thefurniture at the point of supportand with no meansWhatever forabsorbing (shocks between the furniture and the glider. yAsa result, in such construcf tion, the movement of `the, krfurniture over25 floors, andparticularly inthe ycase of Avery hard floors, such asythosewinade ofgmarble, stone, concrete, etc., caused .a r` eat deallofnoise. v,This is averyundesira 'le effect, es# pecially in thecase oflarge rooms or halls Where a large number of'chairs are being ymovedfata given time, as-will be readily understood. 1 Attempts Vhave beenA madeat the time to absorb all shocks between the gliders andthe furniturebut in those constructions a number of .disadvantages have developed.

Such f previous constructions have had such a tight union between the?glider .and the article of furniture as to transmita" considerableamount of .noiseunder [certainc'irf40 cumstances when! moving`the-furniture.

Furthermore, in vsome instances the-construektion .was suchy as not l toeffectively hold fthe glidergcap, which4 contacts 'with thev floor sebcurely in position so thatsuch caps :ofttimes became dislodged anddestroyedtheeffectivestances, in previous constructions, in ,the-en- 1;-While my invention is capable dtvof secuie'th cap'tighuy in' piacea fhas been found necessary .to makethe cap of nitureto be moved.Also,vsuch soft metal` cOIlStructions have been foundfto make decidedmarksjon' some Hoor-coverings, such, for example, asflrinoleum..Furthermore, in the yeffortfto hold such caps in place it has been foundthatthe material contained ytherein has y become ypacked k-so tightly-asto prevent a resiliency such as is necessary-tojprevent kthe making ofunnecessaryA noises-when ymoving they furniture. i 1

`The object 0f my invention iS, therefore, rto,y i,

avoid these difficulties. Especially, it is one of myobjects to hold thestem` in permanent union kwith the ,cap but with a loose connectionthereto so as topprovide an amountk of free playbetween the` stemattached to the furniture and the capv secured thereto,'soas to enable amaximum resiliency to beobtained by ,reason of the interposed body of`resilient material located. between the furni-y ture and the-capsupporting the same. l A furtherobjectis to permit in this manner, not

only a resiliencyin a vertical directionbe-y tween the-furniturefand thecap,-but1in a lateral direction as well. lA 'resiliency in the lateraldirection .is important as rit has been yf(, 1.lndtha`t shocksffwhichmight be 'transmitted jlat'erallybetween the glider and the furnitureinsliding the; lattery over the floor, v y

, In the opera-tiori of my invention, referring first', 'to'the'termoli; my inventions shownr in Figures l to 3, it will be understoodglider is attached to the furniture, as, for example, the leg of thechair 8, by driving the stem 4 into the same,fthe spring 2 being formedto press at its center against the inside of the cap so as to hold thehead 5 against the cap l. This can be done eithervvith the parts.'assembled or withcthe cap removed followed b vthe final applicationy ofthe cap l-totheremainder of the construction. Howerera.it1SrPfe1sreb1yt0 apply the slider to the furniture in Y Completely assembled onrn,especially as it is desired to have the rubber Washer 'rnore or lesstightly clamped betweeirthefeap land the leg 8 of the chair. This is forthepurpose, as pointed out above, of causing the furniture to becomesupported irrnly from theleap' 1', wh-i'uh.y i'sin turn' supported fromthe Hoor, and, also, so aste-'provide aafirm position for the furniturewhich is cushioned, not' only in a vertical direction from the cap v l?,but,`aljso, in a lateral direction Y dueV both to the loose connectionbetween the stein 4 and the cap 1, and between the inn'e'rcoilsof' thespring 2 withregard to theeap'l. i

` When' the 'article of `furniture', as', for eX-v ample, acliair'-, isbeing'slide overaiioor, it

Wiljl be: seen that there is-an edective cushioning between? thefurniturefand the capY l, due to the rubber Washer 7, thuseliminatingnoise which would otherwise result. Alsofor the reasonszjustexplained', anyr tendency of the ItoE resistmovement' `laterally and'thus produce noise, Will be compensated for by reason of' the cushioninge'ectvbetween the capI l' andthe legi V81 "of the chair. This is veryyimportantes ithas'beenl foundthat such later-all' resistance on the partof movement of the capproduces verticaly component, ref sultinginafgreat deal of noise unless thel construction is such as to eliminatethe saine.
